MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs and a visual lure suggesting a download or reward. The ML classifier strongly flagged this PDF as malicious, and the presence of external URIs points to a potential phishing or malware distribution attempt. Although no scripts were explicitly extracted, the PDF structure and embedded content suggest it's designed to redirect users to malicious sites like https://netcdn.xyz/app/406889139/coin-master-free-spins-link-2021-today-game-hack.

  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
